To alt' ill/wm, t may con/cern,.-

vBe `it known that BEEK, citizen of the United States, and :i

resident'of Hartford, in the county olHart- 4ford and State of Connecticut, have invented a certain new and Improved Universal Joint,

' of which the following isa specit'ication.

My invention relates to the class of devices 'lfoi transmitting power between two members located at an angle each to the other,

and the object ol' my invention is to providea device olV this class, having an outside lever-A age as far as possiblefroin the center, including a supporting membei; a further object of the invention is to provide al device in which the parts may-be readily separated for the purpose of renewal, or for any other purpose;

"a further object of the invention is to provide means for self lubrication of all parts vof the structure in a thorough manner and a further object lis to provide a structui'e that shall be eilectually protected from grit and dirt; and a still further object is to provide a device which shall occupy but little space as compared with the strength thereof and one which shall at the same time contain the greatest simplicitjiv as to the construction ot' v the parts.

@ne form of device in Vthe use of which these olnects may be 'attained is illustrated in the accompanying drawings, in which-- Figure 1 is a view in side elevation of e structure embodying my invention with i parts broken awa).Y in central section to show' l construction. Fig. 2 is a sectional view of the binding` rin-g. liig. 3 is an edge view of the same. Fig. 1 is a detail view perthv in section of the binding ring slimviiig a modi lied form of the invention.

rhile devices for transmitting power be.- tween two members located at an angle each to the other have long been employed, the rapid advance which being made in inechanical construction in certain lines has greatlv enlarged the tield for devices ol' this class. In the field now occupied by such devices the requirements are ver) exacting and necessitate a universal lioint or connection so constructed as to successfully resist excessive strains, and at the saine time reduce to a minimum the friction caused by the relative movement of the parts the requirements also necessitate a joint or connection that shall require little attention, and that shall be thoroughly protected from exposure to- I, ABRAHAM VANnEul l l i l i l i i l l l Specification of Letters Patent.

A device constructed to embody such features is illus tratcd in the accompanying drawings and tinlnaces as yessential parts bifurcated or forked stems 1 and 2 which may be provided with an); suitable means tor connectionwith the driving and driven parts; a bearing and binding member 19 surrounding the bifnr cated stems; removable studs T borne'bjv the forks; a central supporting part 11? for supporting the inner ends of the studs, this cen t'iral mein ber also acting as a receiver and distrilniter for lubricant; and protective washers for closing the bez'trings against the entrance of dust, dirt or moisture.

rl`he forks 3mi and 5 shown in the draw ings, one of the forks being broken away from the stein 2, have openings formed therein for the reception of the pins T. These openings are beveled as at G to receive the tapercd surface on the pins 7. Each of the pins is thi-aided as at. S to tit a threaded surface in the forked member, and on ay reduced lpart a thread 0 of ditferent form is provided which engages with the thread of o lock nut 10. Each of the pins is further reduced as at 11 to engage an opening in the block 12, which forms a central supporting member. The openings Yfor the reception of the pins T-in thisl block 1'2 extend through from side tov side, these openings of course communicating with each other at theccntei of the block and forming an oil reservoir 5. Each `of the pins T is provided with an oil passage 14 communicating with an opening 1:3 extending radially therefrom to the surface of the pin. ln one of the pins this oil passage 1-l extends to the outer eu-tl ofthe pin, said pu$ sage terminating short of the end of the pin in each oll the other instances. This passage is provided with a cup or cover 1t), and the, passage extends to the enti of the pin for the purpose of providing means for supplying oil to the oil reservoir.

.'lhe openings for the pins (j in the block 12 are made oll sutiicient depth to allow for the insertion of a packing 17 located between a shoulder on the pinand the bottom of the pin socket to prevent. oil from leakingoutat these points, and to prevent the entrance of dirt and grit.

.Each of the stems between the forks tapered and rounded as at 1S, the `round surfaces being provided to conform tothe outer end of the opposite vtoi-k, `and tc tapereda swinging movement of the anks to'any spect tothe axisot1 the opposite shank.

It will be notedthat theinoii'ths of the openings are locatedwithin theboundary of this ring to provide a proper lubricanttherefor, and -the packing rings orwashers 23. prevent the entrance of dust to vthe bearing'surfaces between the fork members and pins.- Y

In Fig-4 of the drawings. I have shown a modification of the invention. 'Iii this -formof the device the ring 19a ,is provided with a the lattened surface or bearing 2()EL for the surface of the forks.

' flange or bushing 25 one end of which forms j l reception oi the outer The pins hereinbefore described, (one,'however, only fitted with the lock nuts 10.. In this forni of device the ring is formed with less difficulty and the construcj tion is therefore desirable in some instances.' This structure is provided with a packing ring 23?L and springs 24@ iii the structure hereinbefore described.

By the construction difficulty and they provide a removable stud for the reception of the ring which may be easily renewed The ring may be also hardened i'iculty and thus provide liarj wear t :in y time. with little di deiied surfaces to resist betweenthe pins and the vring at which -point it is obvious.

the greatest wear will occur.

While there has been shown in the drawings herein a dust washer oi' special construction, it will be obviousthat the device de-f Y scribed and claimed herein `is usable withl any A forni ot dust washer without regard to its specific construction.
